In the past I'd always run A/S tires on Subies and an Audi S4 I had for a season (similar AWD set-ups). Both got around fantastic in the snow...even lowered (4" or less ground clearance). This past winter, however, I had a set of tires fail me...slid for over 30ft on icy level pavement at 25mph when someone locked up their brakes and collided with them nearly totaling my car. After looking up reviews on these alleged A/S's I would never put that tire on any car that would see snow again...they handled great in wet and dry but Yokahama Avid Envigors are possibly the worst tire I've ever ran in that circumstance...I instantly opted for Bridgestone Blizaks and the difference between any A/S tire I had driven on was night and day...cornering improved, comfort and the added peace of mind was a nice addition as well.
